Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Vertical Cycle
The vertical scan interval, including the vertical
blanking interval, should be set in raster line
units.
When in TV sync mode, the EXVSYNC rising-
edge detection interval time should be set. If not
detected within the interval, the result is
reflected in the TVR flag in DSSR.
